[0004] The above structure also has the following drawbacks:

[0005] Existing counterbalance forklifts are inconvenient to adjust the angle of their buckets during use. Furthermore, when the bottom of the items being transferred is unbalanced, it is necessary to manually add counterweights, which not only increases the operational risk but may also damage the items being transferred if the counterweights slip. Therefore, there is an urgent need for a counterbalance forklift with an anti-tipping device that can tilt to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a counterbalanced forklift with an anti-tipping device that is easy to adjust, thereby solving the problems mentioned in the background art.

During transport, the forklift body moves the bucket to one side, lifting the goods. When the goods are unbalanced, the drive motor is activated, rotating the threaded rod and causing the positioning block to move upwards. The system levels any uneven areas at the bottom of the goods. After leveling, the lifting mechanism raises and lowers the goods to the designated position. Then, the second cylinder is activated, which moves the lifting mechanism to adjust the tilt angle of the goods. If the goods are not adjusted to the designated position, the first cylinder is activated again, which moves the lever to readjust the tilt angle. This system offers the advantage of convenient adjustment and solves the problem of existing counterbalance forklifts where it is inconvenient to adjust the bucket angle. Additionally, when the bottom of the items being transferred is uneven, manual shims are required, which increases operational risk and could potentially damage the items if the shims slip.

When the goods are unbalanced, the drive motor 56 is turned on, which drives the threaded rod 57 to rotate, causing the positioning block 53 to move upward, thereby leveling the unbalanced parts of the goods. After leveling, the lifting mechanism 2 lifts the goods to the designated position. Then, the second cylinder 6 is turned on, which drives the lifting mechanism 2 to move, thereby adjusting the tilt angle of the goods. When the goods are not adjusted to the designated position, the first cylinder 42 is turned on again, which drives the locking rod 44 to move, thereby readjusting the tilt angle of the goods. This design has the advantage of convenient adjustment.

[0025] In some embodiments, the L-shaped seats 31 are all fixedly installed on the front and back of the lifting mechanism 2, the positioning rods 32 are fixedly installed on the relatively close side of the L-shaped seats 31, and the locking rods 44 are all rotated on the surface of the positioning rods 32 by bearings. More specifically, the positioning rods 32 are fixed by setting the L-shaped seats 31, and the top of the locking rods 44 is limited by the cooperation of the positioning rods 32 and the bearings.

[0026] In some embodiments, the positioning seats 41 are fixedly installed on both sides of the left side of the lifting mechanism 2. The first cylinder 42 rotates in the inner cavity of the positioning seat 41 through the positioning pin. The slot 43 is opened inside the locking rod 44. More specifically, the positioning seat 41 is used to limit the right side of the first cylinder 42, and the first cylinder 42 is used to adjust the angle of the locking rod 44.

[0027] In some embodiments, the left side of the first cylinder 42 extends into the inner cavity of the slot 43 and is rotatably connected to one side of the inner cavity of the slot 43 via a positioning pin. The bucket body 51 is fixedly installed on the left side of the lever 44. The through slot 52 is opened inside the bucket body 51.

More specifically, the threaded rod 57 is driven by the drive motor 56, and the height of the positioning block 53 is adjusted by the threaded rod 57.

[0030] In some embodiments, the slider 55 slides inside the groove 54, and the side of the slider 55 that is relatively close to the positioning block 53 is fixedly connected to both sides of the positioning block 53. More specifically, the slider 55 is limited by the groove 54 to prevent the slider 55 from shaking during movement, and the positioning block 53 is limited by the slider 55 to prevent the positioning block 53 from shaking during movement.

[0031] Working principle:

[0032] Step 1: During handling, the forklift body 1 drives the bucket body 51 to move to one side and lifts the goods under the action of the bucket body 51. When the goods are unbalanced, the drive motor 56 is turned on, and the drive motor 56 drives the threaded rod 57 to rotate, so that the positioning block 53 moves upward, thereby leveling the unbalanced part of the bottom of the goods. After leveling, the lifting mechanism 2 lifts and lowers the goods to the designated position.

[0033] Step 2: Next, open the second cylinder 6. The second cylinder 6 drives the lifting mechanism 2 to move, thereby adjusting the tilt angle of the goods. When it is not adjusted to the designated position, open the first cylinder 42 again. The first cylinder 42 drives the locking rod 44 to move, thereby readjusting the tilt angle of the goods. This has the advantage of convenient adjustment.
